WINDOW REGULATOR.

Application filed October 19, 1920. Serial No. 417,940.

To allwhomz't may concern: 1 l

Be it known that I, Gnonen WELLS, a citizen of the United States, resident of Amesbury, in the county of Essex and State of Massachusetts, have made a certain new and useful Invention in Window Regulators; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a side view of adoor frame, having the invention applied thereto.

Figure 2 is a central horizontal section of the same.

Figure 3 is a detail side view of the handle levers 26, viewed from the side opposite that shown in Figure 1. p

v Figure 4: is an enlarged fragmentary detail view, approximating the position of the parts shown in Figure l, but with lever 8 moved sufficiently to allow lip 22 to seat upon strip 30.

Figure 5 1s a central horizontal section,

showing lip 22 seated upon strip 30.

Figure 6 is a detail cross-sectional view of the bracket 21, with roller 19' engaging the guideway thereof.

Figure 7 is a side view of the same.

The invention has relation to window regulators, designed for use in the raising and lowering of glass windows of closed automobile bodies,and for other purposes, an object being to provide improved means to hold the window at any point in its adjustment; to apply the device to the door frame with a minimum of cutting of said frame in the installation; to provide a device fitting within the well within which the window works, with no projecting parts upon which clothing of the car occupants can catch; to provide a device operable-by a mere push in one direction or the other of. the operating handle orlever, thereby guard ing against accident through incorrect operation. Other objects and advantages will appear.

The invention consists in the novel construction and combinations of parts, as here-. inafter set forth. I

In the accompanying drawings, illustrating an embodiment of the invention, the

numerals 2, 2 designate the upright pillars of the door frame, provided with lateral channeled guides 3, 3', slidably engaged bythe lateral edges of the glass windowi, a transverse member or bar 5 being secured at its ends at 6, 6 within notches of said pillars, and carrying an arc bar 7.

An operating lever 8 is fulcrumed at its lower end at 9f to a bracket'10,. secured within a notch'll of the lower rail or frame bar 12 ofjthedo'or frame, said lever having a rigid angular extension 13, pivotally connected at its outer end at 13 to a linkl l,

the latter being pivoted to a second lever 15, Y

fulcrumed at its lower end at 16 to a bracket 17, secured within a notch 18 of one of the pillars 2, and at itsupper end carrying a roller 19,traveling in a straight track or guideway 20, located in a bracket 21,,carried by a channeled metal strip 22, within the longitudinal recess of which is engaged the,

lower edge of theglass window 4. I

A counterbalancing coiled spring 23 is secured at its outer end to an eye 24:, engaged with a pillar 2 of the door frame, and at its other end has connection with the operating lever at 25, Y

Handle levers: 26, 26, are fulcrunied at.

their lower ends at 27 to the operatingilever, and at their upperends carry each a laterally projecting stud 2,8, grooved to engage the upper edge of the arobar .7, coiled springs .29, engaging seats of the, handle levers between their fulcrum ends and said studs, serving to normally maintain Said,

levers each oblique to the operating lever and .oppositely inclined relative to each other,-the' studs 28 being thereby engaged frictionally with the upper edge of said are bar and effectually resisting. any move.' ment of the operating lever in .eitherdirection, and thereby preventing any move-j ment of the window either upwardly or downwardly, except inextremejupper or lower position thereof. l I

The handle levers are movable towards each other as; shown in, dotted lines in Figure 3 of the. drawings, to'releasejthe studs28 from the arc bar, after which the operatinglever may be moved inone .direction or the other in raising or lowering. the

window, the release of the handle levers at any point in the path of the glasswindow from uppermost to lowermost position being followed by frictional bind of the studs 28 upon the are bar to secure the window in position as adjusted.

release of one of the studs 28, by a push upon one of the levers 26 towards the other lever, will be followed by a movement of the operating lever to raise or lower the window as the case may be, the undisturbed lever 26, being oppositely inclined, merely causing a slight frictional resistance of its roller 28 along the are bar which'will not prevent ready adjustment of the window.

The window may be designed for a straight lifting and lowering movement in a vertical path, or it may be designed to have a slight lateral movement at the end portion of its upward movement, and in the latter case, after the operating lever has been moved to the limit in one direction, as shown in Figure 1, the window is pressed laterally, against the tension of spring 3, to move a laterally bent channeled lip 22 of the strip 22 over the transverse rail or fence 30 of the window frame, after which the operating lever is moved slightly in a reverse direction, as shown in Figure 4, to drop said lip upon and over said fence, whereon it will rest and prevent entrance of rain or water to the well in which the window works. In lowering the window the glass is raised to clear said fence, after which spring 3 automatically acts to press the glass laterally to normal position.

As the wood of which the door frame is made sometimes warps, it is desirable to prevent this warpin from disturbing the concentric relation of the arc bar relative to the fulcrum of the operating lever, and to this end the arc bar is pivoted at one end at 31 to the transverse bar 5, and at its other end has a notch 32, within which is engaged a screw or pin 38, thereby admitting of slight pivotal movement of the arc bar upon the pivot 31 as a center, this pivotal movement following automatically in the work ing of the window regulator and insuring its proper working.

The are bar being movable relative to the gripping or handle levers, it is necessary that the operating lever should support the bar against the tension of the levers, for which purpose the extremity of the operating lever lies immediately beneath and in the plane of the are bar. A further advantage of this construction consists in the rigid clamping of the operating lever to the bar, obviating any movement of the parts, due to the vibration of the vehicle and tending to allow gradual movement of the window or to wear the surface of said bar into corrugations which would interfere with the smooth action of the device. This smoothness of action in release, movement and reengagement is further insured by the engagement of the arc bar upon opposite sides by the clamping members.

In the extreme upper or lower position of the glass window, it may be lifted out of the door frame and removed, irrespective of the action of the studs 28 upon the arc bar, inasmuch as in these two positions of the window the roller 19 is located over a cut-out portion 20 of the track 20, thereby providing for replacement of a broken glass witliout disturbance of the window regulator.

In the installation of the invention, it is only necessary to notch the woodwork at 6, 11 and 18, after which the entire assembled regulator is insertable in place as a com plete unit, and thereafter the transverse bar 5 and the brackets 10 and 17 secured in place. The lock rail 34 of the door frame is then placed in position, being provided with a central perforation 35, engaged by a laterally projecting bolt 36 of the transverse bar 5, a nut 37 being engaged with the thread of said bolt and fitted within a recess of the lock rail, whereby the bar 5 is braced against lateral movement.

I claim:

1. In a device of the character described, an arcuate bar, an operating lever movable along said bar, and a spring-tensioned handle lever pivoted to said operating lever and provided with a lateral stud having direct binding engagement with said bar, said handle lever being operable to release and move said operating lever.

2. In a device of the character described, an arcuate bar, an operating lever movable along said bar, and duplicate spring-tensioned handle levers pivoted to said operating lever at one side of said bar and provided each with a lateral stud having binding engagement with the opposite side of said bar, said handle levers operable to release and move said operating lever.

3. In a device of the character described, an arcuate bar, an operating lever movable along said bar, and duplicate spring-ten sioned handle levers pivoted to and projecting beyond said operating lever to form an extension of the same and provided each with a lateral stud engaging said bar and normally resisting movement of the operating lever, said levers being manually operable by movement of their projecting ends towards each other to release and. thereafter operable to move said operating lever in either direction.

In testimony whereof I affix my signature in presence of two witnesses.
